Question

Researchers counted and tagged 638 deer. On their next visit, they counted 105; only 35 were marked. Estimate the total deer population in the area

Answer 1

1914

Explanation:

Let the estimated total population of the deer =x

Out of x, 638 were tagged.

Out of 105, 35 were marked.

Expressing this as a ratio of the total to tagged, we have:

x:638=105:35

`(x)/(638)=(105)/(35) \\$Cross Multiply\\35x=105*638\\x=(105*638)/ 35\\x=1914`

Therefore, the total deer population in the area is approximately 1,914.
